  <p>The LTPDA Toolbox is a MATLAB<sup>&#174;</sup> Toolbox designed 
    for the analysis of data from the LISA Technology Package (part 
    of the LISA Pathfinder Mission). However, the toolbox can be used for
    any general purpose signal processing, and is particularly useful for
    analysis of typical lab-based experiments.
  </p>
  <p>
    The Toolbox implements accountable
	and reproducible data analysis within MATLAB<sup>&#174;</sup>.</p>

  <p>With the LTPDA Toolbox you operate with LTPDA Objects. An 
	LTPDA Object captures more than just the data from a particular
	analysis: it also captures the full processing history that led
	to this particular result, as well as full details of by whom and 
	where the analysis was performed.</p>
